Description

technical field [0001] The invention relates to a communication system, in particular to a high-speed signal optical transmission device integrating transceiver and a signal optical transmission method. Background technique [0002] With the continuous development of 5G communication in my country, the amount of data to be processed and transmitted is also increasing, and the number of signal channels is also increasing. Although the pressure can be relieved to a certain extent by increasing the transmission rate of the signal, the transmission rate The improvement of optical transmission has brought problems such as crosstalk, and the increase in the number of signal channels has also increased the weight of the system, which is unacceptable for important communication systems. The advantages of optical transmission are fast speed, anti-interference, and light weight. Therefore, weapons The signal transmission mode of the system is also gradually converted from electricity to...

Problems solved by technology

[0008] (1) In addition to the coupling circuit, laser modulation and driving circuit, and limiting amplifier circuit, the circuit also includes a microcontroller circuit. Therefore, the principle circuit cannot achieve the design purpose of miniaturization;

[0009] (2) The microcontroller circuit manages the laser modulation and driving circuit and the limiting amplifier circuit at the same time. Therefore, the transceiver channels cannot be electrically independent from each other, and the mutual crosstalk between the transceiver channels cannot be avoided;

[0010] (3) Both the optical and electrical interfaces are pluggable. The optical module is in an open state and cannot be used in shipboard and other application environments. poor environmental performance

[0011] In the existing technology, the scheme and structural design of the general-purpose optical module not only make the product bulky, but also have a complex structure, making it difficult to achieve the technical purpose of all-metal sealing for transceivers
